At the breakfast table this morning, Spud (who's just turned seven) leans across to his ten year old brother and says: "Go on then, give me some algebra - don't make it too hard."
I had to step in after I saw the glint in the Big Fella's eye - he was working up a doozy of an equation for his brother to solve. In the end, he settled for 3x+2=11, which Spud reckoned was a little too easy.
Where do they get it from? At a guess, I'd say their older brother has been sharing some of his book learning with them. Maybe he's been running math seminars for them in between their mammoth Play Station sessions.
Still, it makes a change from the usual breakfast time conversation; I was getting a little bored with comparative theology.
